Merrimack River Mouth Meets the Atlantic

Where the Merrimack Meets the Sea

This live webcam overlooks the mouth of the Merrimack River, the dramatic point where New England's Merrimack completes its journey and empties into the Atlantic Ocean. Two long rugged rock jetties guide the channel seaward, framing a restless meeting of river and tide.

Barrier-Island Beaches and Dunes

In the foreground, the ever-shifting sands of Plum Island stretch toward the water, sheltered by classic timber dune fencing. This barrier-island coastline preserves one of Massachusetts's most cherished stretches of wild shoreline.

A Historic Maritime Gateway

Beyond the sand lies Newburyport, a storied seafaring city whose harbor has welcomed mariners for centuries. The river mouth remains a vital navigational gateway between the jetties and the open Atlantic, a timeless threshold between land and sea.
